Overview
This dataset contains cone-beam CT scans of an Adafruit RP2040 PCB mounted in a snap-on plastic case, acquired on a North Star Imaging (NSI) 1420-DR cone-beam CT system. It is designed as a benchmark for:
- Plastic-metal beam-hardening correction
- Metal artifact reduction (MAR)
- Iterative reconstruction algorithm development and evaluation
The dataset includes scans at three view counts (600, 1200, 1800) in both horizontal and vertical orientations, along with CAD files and a preprocessing script for use with MBIRJAX.

Preprocessing
An example MBIRJAX preprocessing script is provided to reconstruct the dataset:
This script is written for use with the MBIRJAX software package. See the MBIRJAX documentation for installation and usage instructions.
